- Deep layers of premium pressure-relieving memory foam

Four Layer Construction
-
CoolGuard™ Cover with Revo® Cool Gel
The cooling here isn't a loose pad that goes missing — the gel is sewn straight into the zip-off cover, so the cover and the cooling are one and the same piece. You feel the coolness the second you drop onto the bed after a long drive, and it keeps working all night; laboratory testing puts it at 30× more breathable than ordinary memory foam, so heat has nowhere to gather in a closed-up van. When it needs freshening, unzip the cover and the cool-gel layer comes away with it.
-
Vasco®60 Premium Memory Foam
Top-grade memory foam that warms and gives way beneath you, moulding around your shoulders, hips and the small of your back so pressure lifts off the points that ache after a day on your feet. It quietly swallows movement too, so a partner shifting beside you on a van bed barely registers.
-
Laytec™ Responsive Support Layer
Under all that plush foam sits a springy support layer that catches your weight and holds your back in a straight line — the reason you can melt into the surface and still wake up properly supported rather than sagging into the base.
-
Premium Foundation Layer
A firm, breathable base that anchors the whole mattress and keeps its shape through years of use, yet stays light enough to shift and manoeuvre in the tight quarters of a van.
Why Choose Grand Crescent?
Memory foam gives you that lovely sink-in, wrapped-up feeling — the catch is that it normally hangs onto your body heat, and a sealed van warms up fast. The Grand Crescent™ is our answer at the top of the range. The memory foam is genuinely deep, so you settle into it and it cushions every pressure point, while the support layer beneath keeps you held in place. And with the cooling gel built into the cover, none of that comfort arrives with the stuffiness memory foam usually brings.
It's for the owner who's put real money into their conversion and wants the bed to live up to the rest of it: four layers of genuinely premium materials, offered in our two deepest builds, with the foam standing behind an 8-year guarantee.
Ideal for:
- Van owners who love the hug of memory foam but overheat on it in a closed-up cabin
- Anyone after deep pressure relief that's still held up firmly from below
- Couples on a shared van bed — the foam soaks up movement, so you feel less of each other's turns
- Anyone kitting out a high-end conversion who simply wants the best mattress we make

Measuring Guide
We cut the foam to the exact measurements you send us, and the cover then adds a couple of millimetres to the final size.
If your bed drops into a snug recess — as it often does in VW and coachbuilt conversions — or you want a little slack for tucking bedding in, trim your figures down a touch. That part's purely personal preference.

Frequently Asked Questions
- How do the memory foam and cooling work together?
- The foam moulds around you and lifts pressure off your joints, while the gel in the cover pulls warmth away from the surface — you get everything people love about memory foam without the heat it normally holds in a warm van.
- What do the four layers do?
- Beneath the memory foam is a responsive layer that pushes back as you move and keeps your spine level, and under that a steady, breathable foundation. Between them you get soft contouring on top and genuine support below.
- How long does a rolled mattress take to expand?
- Give it 1–2 hours to open out to shape, then 12–24 hours for the cooling and the responsive layers to fully find their feel.
- What's included?
- The mattress itself, its zip-off cooling cover, your care instructions, and an 8-year guarantee covering the foam.
- Is the Firm option suitable for everyday use?
- Definitely — it's built to give back-and-joint support night after night while still sleeping cool, and it works whichever position you settle into.
